The specific embodiment

Referring to Fig. 1, present embodiment is by active handle 1, passive handle 2, upper clamp 4, lower clamp 3 and catch bar 5 and 6 interconnection compositions of lock screw.

Referring to Fig. 3, initiatively be provided with the passive handle chute 7 of indent in the handle 1, and initiatively have the screw hole 8 that is complementary with lock screw 6 sizes on the handle 1.

Referring to Fig. 4, passive handle 2 is provided with the active handle slideway 9 of evagination, and has the draw-in groove 10 of indent on the passive handle 1.

Referring to Fig. 5, an end of catch bar 5 is provided with the bayonet socket 11 and the spacing seam 12 of evagination, and the other end of catch bar 5 is provided with the catch bar slideway 13 of evagination.

Referring to Fig. 6 and Fig. 7, the outer wall of upper clamp 4 is provided with the lower clamp chute 14 of indent, is provided with the catch bar chute 15 of indent in the upper clamp 4.

Referring to Fig. 8 and Fig. 9, an end of lower clamp 3 is provided with the locking nest 16 and the stopper slot 17 of indent, and the other end of lower clamp 3 is provided with the upper clamp slideway 18 of evagination.

Referring to Fig. 1～Fig. 9, initiatively handle 1 links to each other with active handle slideway 9 by the passive handle chute 7 that matches each other with passive handle 2, and initiatively handle slideway 9 and passive handle chute 7 are circular-arc, and initiatively handle slideway 9 is positioned at passive handle chute 7.The end that lower clamp 3 is provided with locking nest 16 and stopper slot 17 is positioned at initiatively handle 1, and wherein screw hole 8 is corresponding with locking nest 16 positions.The end that catch bar 5 is provided with bayonet socket 11 and spacing seam 12 is positioned at the initiatively junction of handle 1, passive handle 2 and lower clamp 3, and wherein spacing seam 12 is positioned at stopper slot 17, and the size of stopper slot 17 is greater than spacing seam 12, and bayonet socket 11 is positioned at draw-in groove 10.Lower clamp chute 14 and the upper clamp slideway 18 on the lower clamp 3 on the upper clamp 4 all are circular-arc, and upper clamp slideway 18 is positioned at lower clamp chute 14, catch bar chute 15 and the catch bar slideway 13 on the catch bar 5 on the upper clamp 4 all are circular-arc, catch bar slideway 13 is positioned at catch bar chute 15, so just upper clamp 4 and lower clamp 3, catch bar 5 is connected together.Lock screw 6 is positioned at screw hole 8, and lock screw 6 is corresponding with locking nest 16, and promptly an end of lock screw 6 is positioned at the locking nest 16 of indent, thereby lower clamp 3 is positioned on the active handle 1.

Five parts are by together interconnection with the upper hopper chute ways of connecting, and wherein passive handle 2 can rotate around active handle 1; Catch bar 5 can translation in lower clamp 3 under the drive of passive handle 2; Under the promotion of catch bar 5, upper clamp 4 can rotate with the center that is connected of lower clamp 3 around it, the motion of catch bar 5 is subjected to the stopper slot 17 on the lower clamp 3 and the effect of spacing seam 12, can only move in certain distance, thereby guarantee the size of the rotational angle of upper clamp 4.One side of the spacing seam 12 of projection is spacing seam left end 12-1, its opposite side is spacing seam right-hand member 12-2, when upper clamp 4 and lower clamp 3 are opened, spacing seam left end 12-1 moves to the left end of stopper slot 17, up to limited and can't continue to move, open angle maximum between upper clamp 4 and the lower clamp 3 at this moment; When upper clamp 4 and lower clamp 3 were closed, spacing seam right-hand member 12-2 moved to the right-hand member of stopper slot 17, and up to limited and can't continue to move, at this moment upper clamp 4 is just in time closed with lower clamp 3; In addition, the effect of spacing seam left end 12-1 and spacing seam right-hand member 12-2 is also interchangeable, as long as the corresponding change of the aperture position of stopper slot 17 on catch bar 5.

When needing dismounting, unclamp lock screw 6, passive handle 2 is rotated counterclockwise, the being slidingly connected part between passive handle 2 and the active handle 1 is separated, passive handle 2 can take out downwards; Then lower clamp 2 and catch bar 5, upper clamp 4 together translation take out, after catch bar 5 separated, upper clamp 4 downward dextrorotations went to the below of lower clamp 2, lower clamp chute 14 and 18 disengagings of upper clamp slideway, upper clamp 4 promptly separates with lower clamp 2; Change in last catch bar 5 clockwise directions, catch bar slideway 13 breaks away from catch bar chute 15, and lower clamp 2 promptly separates with catch bar 5.Wherein lock screw 6 is loaded onto back non-disconnectable time, but can unclamp.

Described lock screw 6 also can be tapered end, spring etc., as long as can play lower clamp 3 is positioned at effect on the handle 1 initiatively.

The shape of cross section of described catch bar 5 can be square, also can be circle, as long as its shape and size are complementary with lower clamp 3.The material of catch bar 5 can be metal or other material.
